Wanaque and Ringwood police investigated after Schaffner posted a countdown clock on Instagram using his real name, they said.

Schaffner’s Facebook page says he recently served as an intern in the “finance and clerk’s offices” of the borough of Ringwood and previously worked at Spring Lake Day Camp in town.

Records show he received a Young Mentor Award for assisting the Ryerson Middle School robotics team at the Montclair Society of Engineers first LEGO League state tournament, held at Clifton High School, in 2016.
